Fig. 2 is electric defrosting refrigeration system principle figure.
Specific embodiment
The embodiment of the present invention is described in detail below in conjunction with attached drawing, but sheet is practical to be defined by the claims
Implement with the multitude of different ways of covering.
See Fig. 1-2, efficient energy-saving electrothermal defrosting and refrigeration system, including compressor 1, evaporation tube 2, dew eliminating tube 3, condenser 4,
Device for drying and filtering 5, solenoid valve 6, capillary 7, evaporator 8 form the circulatory system by pipeline with upper-part,
Specifically, in the present embodiment, compressor 1, evaporation tube 2, dew eliminating tube 3, condenser 4, device for drying and filtering 5, solenoid valve
6, capillary 7, evaporator 8 are successively end to end, form the circulatory system.
The course of work of the present embodiment system is as follows:
Cooling stages: opening equipment power supply, and electric-control system enters refrigeration shape to the present embodiment system input voltage, system
State, solenoid valve 6 is opened and compressor 1 starts, and compressor is by absorbing the refrigerant steaming come the low-temp low-pressure in flash-pot 8
Vapour has ultimately become the steam of high temperature and pressure after the adiabatic compression of compressor 1, and high temperature and high pressure steam is through 1 row of compressor
Tracheae enters the condensed water being discharged after evaporation tube 2 or defrosting is dripped.Secondly, high temperature and high pressure steam, which flows into dew eliminating tube 3, makes anti-dew
Pipe 3 generates heat, and then, the steam of more high temperature enters in condenser 4, and the condensation of refrigerant vapour is carried out under same pressure,
It radiates simultaneously by the peripherad medium of fan of condenser 4, is become the cold liquid of refrigerant of high pressure low temperature.Refrigerant
After cold liquid passes through 5 dry filter of device for drying and filtering, flows through solenoid valve 6 and enter in capillary 7, the cold liquid of the refrigerant of high pressure low temperature exists
In capillary 7 after isenthalpic throttling, it is converted into the refrigerant moist steam for low-temp low-pressure, later send refrigerant moist steam
Enter in evaporator 8.Make its boiling under conditions of 8 equipressure of evaporator by the low-temperature low-pressure refrigerant moist steam of capillary, makes
Cryogen moist steam can absorb the heat of surrounding medium during boiling, ultimately become the dry saturation of refrigerant of low-temp low-pressure
Steam is finally absorbed from the low-pressure steam that evaporator 8 flows out by compressor 1, and when being in refrigerating state, the above-mentioned course of work is continuous
Circulation.When temperature reaches set temperature, compressor 1 is shut down solenoid valve 6 simultaneously and is closed, when temperature rises to specific temperature, system
Cooling system starting, repeats above-mentioned refrigeration cycle.
The defrosting stage: when electric-control system detects that system needs to defrost, control system can be automatically into defrosting state, at this time
Compressor 1 stops working and solenoid valve 6 is closed.When defrosting, heat-generating pipe work defrosting so that evaporator 8 heats up of electric-control system,
After defrosting, system is automatically into refrigeration cycle mode.
Further, it is connected between the compressor and evaporator by low-pressure gas pipe.
Further, it is connected between the compressor and evaporation tube by high-pressure gas pipe.
Further, the evaporation tube, dew eliminating tube, condenser, device for drying and filtering, solenoid valve, capillary, evaporator be successively
It is connected by liquid line.
Further, the evaporation tube is water pond shape.
Further, the dew eliminating tube is door frame.
Further, the solenoid valve is used for partitioning system circuit.
These are only the preferred embodiment of the present invention, is not intended to limit the utility model, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should be included within the scope of protection of this utility model.
